General Engineering Engineering is a very broad topic and branches into many different areas of society. Circle what you think are engineered: List 5 attributes which engineers portray: 1. 2. 3. 4. 5. 6
1. What is the difference between a regular aircraft and a glider? 2. Show the forces acting on an aircraft: - Using Lift, Thrust, Weight & Drag 3. Match the force on the left with its correct statement Lift Caused by gravity Thrust Generated by the wings; this force counteracts weight Weight Caused by air resistance Drag Generated by the engines (or by throwing your gliders!) 8
4. Where in the atmosphere does: i. An Aircraft fly during its cruising phase of flight? (Circle the number on the diagram) ii. A Glider during flight? (Circle the number on the diagram) 9
5. Complete the sentences below to show how you might control the flight of a glider using the following answers: Pitch, Balanced, Horizontal Stabiliser, Symmetrical, Roll, Vertical Stabiliser Making sure that your wings are __________ and ____________ will help to prevent _________. In order to control _________ you need a __________ and a good weight balance A ______________ helps to prevent yaw. Important for maintaining straight and level flight! 10
Anhedral and Dihedral Wings: Anhedral Wing tips are below the attachment point on the aircraft’s fuselage (see diagram below). This makes the aircraft less stable during flight, but gives greater manoeuvrability so you will find these on fighter/military aircrafts usually. 11
Dihedral Wings tips are above the attachment point on the aircraft’s fuselage (see diagram below). This gives an aircraft more stability so you will find them on transport and airline type aeroplanes. 12
6. Using the information you have just learnt, can you circle all the aircrafts (below) that have Anhedral Wings? 13
Activity 2: Lift & Drag 14
Flight Dynamics (You will not have control surfaces or engines on your glider) 1. Match the glider part with its role Wing Gives glider stability in pitch Provides the lift which counteracts the Fuselage weight of the glider. Long and thin shape. Separates the “tailplane” from the wing Vertical Stabiliser and the centre of gravity. Also carries (Fin) payload (passengers or cargo) in a large aircraft. Horizontal Stabiliser Gives glider stability in yaw (Tailplane) 15
2. Show how a wing creates lift When the smooth air flow is disturbed, you get drag. The shape of your glider determines how much the air flow is disturbed. 3. What effect does drag have on your glider in flight? 4. How can drag be reduced? 16
Drag Activity 5. Number the aircrafts from the highest (1) to the lowest drag (4). 17
Activity 3: Materials & Manufacturing 18
1. Match the material qualities with their definitions. Material Quality Definition Low Density Easily shaped (at High Temperatures) Ductile Very strong Malleable Low weight for a given size Corrosion Resistant Bends and stretches before breaking Design Flexibility Long life and requires minimal maintenance High strength It does not rust Durable Can be formed into very complex shapes 2. Which of the above material qualities do these materials have? Composites: Aluminium: 3. What is the difference between ferrous and non- ferrous metals? 4. What is the scientific name for plastic? 19
5. What is the difference between a thermoplastic and a thermosetting plastic? 6. What should you consider when choosing aircraft materials? 7. Name 3 methods for joining aerospace materials 1. 2. 3. 20
Activity 4: Flight Testing 21
Brief Flight testing is a critical stage in the design of aircraft. Up until flight test, the aircraft will only have been tested by computer modelling, simulation and ground testing. Flight testing allows us to see how an aircraft actually performs in real life. During flight testing we can continuously modify and improve the aircraft design. Typical commercial aircraft flight test campaigns last over a year and entail the aircraft flying over 2,600 hours. During this activity you will perform your own mini flight test campaign. On the next page you will find the template of an aircraft. Stick the template onto a piece of cardboard and then cut out all the thick black lines and thick green lines only (make sure you have supervision when cutting out the aircraft). The wing and tail should then be able to slot into the two slots you have cut out in the fuselage. Your aircraft is now ready for flight testing. Give it a throw and see how it flies! During the flight test campaign you can now modify your aircraft in the following ways: Fold left or right along the thick orange line to adjust the rudder. Fold up or down along the thick orange line to adjust the elevator. Fold up or down along the thick orange line to adjust the ailerons. Add ballast such as bluetac to the blue ballast circle on the nose of the aircraft. Some of the modifications above will make your aircraft fly better and some will make it fly worse. Experiment to find the best modifications. 22

Activity 5: Design and Build Activity 25
Brief Using recyclable materials at home, make a glider “like you would if you were at School”. Get creative and make it colourful! Once you have built your Glider, upload it to social media and tag Flying Start Challenge! @FlyingStartChal linkedin.com/company/flying-start-challenge @flyingstartchallenge facebook.com/flyingstartchallenge Here is a list of materials which you could use: Cardboard toilet rolls Juice/Milk cartons Newspaper Cardboard 26
Foil Wood (if using, make sure you have supervision) Paper Plastic bottles/containers (washed out of course) These are just some of the household items which you could use with your glider build. Make sure you have some cutting equipment (e.g. Scissors - but make sure you have adult supervision), some sort of sticking method (e.g. cello tape, glue, elastic bands, etc.) and anything else you think is essential to the build! Good Luck and let’s make things fly!! 27
Activity 6: Plane of the Future Activity 28
Brief Modern commercial aircraft are designed to optimise fuel efficiency and passenger/cargo loading. In the future the priorities are shifting towards making more environmentally friendly aircraft using new technologies and reducing fossil fuel usage. For this activity use the drawing sheet on the next page to design, colour and label what you think aircraft of the future should look like. Include features and technologies that may make the aircraft environmentally friendly and maybe other interesting features that future passengers may enjoy!

Activity 7: Record Breaking Aircraft
Brief Since the first aircraft took to the skies in 1903, many significant aircraft have broken the boundaries of engineering and set new records in the sky. Some are now retired but others still roam the skies and can be seen at airports every day. No doubt there will be plenty more record breaking aircrafts to be designed in the future which you could be a part of. For this activity match up all the different aircraft pictures and names in the grid below. Why not upload a picture of your favourite aircraft to social media and say why you love it.

Activity 8: Moon Lander Activity 35
Brief Build a ‘Moon Lander’ to keep two “Astronauts” inside a cup as it is dropped from 3 different heights. You will have to: Design a Moon Lander Build it Test it Modify it (if the design is not perfect from the start!!) o Then re-test it (if needed) Perform the landing capability of your Moon Lander Take over the universe 36
Design & Build • Keep the design simple, to allow for an easy build – it does not need to be complicated. • Once happy, make sure you test you design and make sure the landing concept works. • If your design needs to be modified, make sure this is considered at the initial stages of the design. • Make your design to be as creative as can be – don’t stick to the statuesque!! Top Tip for Design • Sketch out your ‘Moon Lander’ before actually building it! • Here are some actual examples of Moon/Space Landers used in real life: • Here are some examples of how your ‘Moon Lander’ could look 37
Equipment You can use the following: Sheets of Card Straws Sheets of Paper Masking Tape Plastic Cup 2 Astronauts (2 Table Tennis Balls) Marshmallows or Modelling Clay Landing your Moon Lander: The Moon Lander should be deployed from three different heights: • Troposphere Landing: 1.0m • Stratosphere Landing: 1.5m • Thermosphere Landing: 2.0m Once you have built your Moon Lander, upload it to social media and tag Flying Start Challenge! @FlyingStartChal linkedin.com/company/flying-start-challenge @flyingstartchallenge facebook.com/flyingstartchallenge 38

Answers 42
Basic of Flight 1. Glider: Carries up to 2 people, Long wings, No engines, limited Landing Gear Aircraft: Has some sort of propulsion system, Landing Gear, has multiple systems on-board, can carry more than 2 people 2. 3. Lift = Generated by the wings; this force counteracts weight Thrust = Generated by the engines (or by throwing your gliders!) Weight = Caused by gravity Drag = Caused by air resistance 4. i. 4, ii. 5 5. Making sure that your wings are Symmetrical and Balanced will help to prevent Roll. In order to control Pitch you need a Horizontal Stabiliser and a good weight balance. A Vertical Stabiliser helps to prevent yaw. 6. Lift & Drag 1. Wing = Provides the lift which counteracts the weight of the glider. Long and thin shape. 43
Fuselage = Separates the “tailplane” from the wing and the centre of gravity. Also carries payload (passengers or cargo) in a large aircraft. Vertical Stabiliser (Fin) = Gives glider stability in yaw Horizontal Stabiliser (Tailplane) = Gives glider stability in pitch 2. 3. Drag slows the aircraft down - The shape of the aircraft determines how much drag is produced. 4. To reduce drag, you need a shape which will cut through the air and maintain a smooth air flow. 44
5. (3) (4) (1) (2) Materials and Manufacture 1. Low Density = Low weight for a given size Ductile = Easily Shaped (at High Temperatures) Malleable = Can be formed into very complex shapes Corrosion Resistant = It does not rust Design Flexibility = Bends and stretches before breaking High strength = Very strong Durable = Long life and requires minimal maintenance 2. Composites: Low weight for a given size, Can be formed into very complex shapes, Very strong, long life and requires minimal maintenance. Aluminum: Low weight for a given size, Bends and stretches before breaking, Easily Shaped (at High Temperatures), does not rust. 3. Ferrous metals contain iron. 4. Polymer 5. Thermoplastics can be re-melted back into a liquid, whereas thermoset plastics always remain in a permanent solid state. 6. High strength to weight ratio, durability, corrosion resistance. 7. Rivets, welding, adhesive, screw fasteners, bolts. 45
